Abstract

Apparatus for use when machining or applying a textured finish to a surface of a workpiece (2) comprises a receptacle (12) for containing dielectric fluid which is closed on all sides excepting that side which, in use of the apparatus, engages the adjoining surface of the workpiece (2). The open side of the receptacle (12) carries a flexible structure (17) which can be moved towards and away from the workpiece surface between a first position in which the open side of the receptacle (12) is spaced from the workpiece (2) and a second position in which the workpiece surface closes off the open side of the receptacle (12). The flexible structure (17) carries at its edge surface a resilient member (32, 34) whose contour can be varied to match the contour of the workpiece (2). In a preferred embodiment the flexible structure comprises a bellows-like structure.
